In 2004, Rodrguez-Lallena and Ubeda-Flores have introduced
a class of bivariate copulas which generalizes some known
families such as the Farlie-Gumbel-Morgenstern distributions. In
2006, Dolati and Ubeda-Flores presented multivariate generalizations
of this class. Then in 2011, Kim et al. generalized Rodrguez-
Lallena and Ubeda-Flores' study to any given copula family. But
there are some inaccuracies in the study by Kim et al. We mean to
consider the interval for the parameter proposed by Kim et al. and
show that it is inaccurate.
